Hi folks!!! I Have Panasonic SA-DM3 DVD home Theater Sound System and i wounder where can i buy only Subwoofer and 1 speaker. Thanks!!!

1. Check with one speaker all speaker channels. If no sound probability does not work AMP board .

The amplifier is over heating. Probably the emitters, drivers and voltage regulator is bad. I suggest a clean sweep replacing the power pack integrated amp, all emitters, mosfet regulator, and SRC power switch start up control.

It is always wise to tell us if this is new equipment or a spontaneous failure on previously functioning equipment. I'm guessing this the former.

For starters you could look at the manual.

See page 5. >>>>>>>>>>>>>>> STEP 1 <<<<<<<<<<<<<<< - Orienting the unit and attach the feet.

Its physical orientation is wrong, possibly upside down.

Believe it or not there is a seller on eBay who offers a one-price fixit solution for your unit for $100.

That aside, these types of systems are designed as a package to be used as a unit. Otherwise they might have standard connectors. Another closely-related Panasonic SA-HT system might work for you but I doubt anyone manufactures anyhting to adapt non-standard speakers to standard electronics.

They actually say on page 9 of the manual:

"Use only supplied speakers
Using other speakers can damage the unit, and sound quality will
be negatively affected.

I would interpret that to mean 'use these speakers only with similar Panasonic electronics'.

ANY amp will be ok, as long as the wattage of your new amp does not exceed the wattage of your speakers. Otherwise you could overdrive your speakers and damage them. First clue, if you turn up the volume and the speakers start to shut off and on you are pushing too much power to them.

the difference is the "same speaker connections"
the front and rear will connect the same but the subwoofer is amplified by the HT75 , and the HE75 does not have an internal amp for the subwoofer speaker , only a "pre output"(has to be amplified)

your speakers will still make sound if blown, it just wont be good sound, are you sure you have all the cables connected correctly?

MY model is not in the site of panasonic, what is the problem? SA_PT560 a home theater with 4 standed and a subwoofer and a center speake, but as i said my model is not in the site! what's the problem?

unplugged a Panasonic HDTV plasma for four minutes, plugged back in and Now the DVD does not work.

How to reset?
